Aztec launches Tierra (Alpha V6) with critical fix and faster proofs

The Aztec Foundation introduced Aztec Tierra (Alpha V6), a network upgrade for its privacy-focused Ethereum layer 2, in an announcement amplified by the Ethereum account on X. The release fixes a critical vulnerability found in the previous V5 version, adds security hardening, and includes formal verification of core cryptographic components plus an AI-powered testing harness.

Performance gains include client-side proofs generated in roughly one second on a standard device — about twice as fast as before — and Ethereum-to-Aztec messages delivered in as little as 12 seconds, down from an average of two minutes.

• Ships with a refreshed brand and website, plus a slate of private apps led by the revived zk.money payments app
• Other launches include Galactica (private AI inference), Nemi (private perpetuals), the Nulo wallet, and Rolling Chat
• Aztec describes itself as Ethereum's only decentralized L2 with fully programmable privacy — no backdoors, no gatekeepers
